Patented `lan. 7, 1930 UNITED STATES JOHN R. SMITH, OF LOS ANGELES, CALIFORNIA SILENT JET, AIR-VENTING, REFILL TOILET BOWL Application led August 16, 1929. Serial No. 386,366.

o bowl in the least time from start of spray, to

eliminate travel of a mass of water in the rim to fill the rim all around for wash down shower at each flush; to maintain a constant supply of water in the rim at all times; to reduce the volumel of air content in the rim as compared with types of rims with jet holes for wall jets, and to effect a removal of odorous air from the bowl by use of the flushing water entering the bowl.

More specifically an object is to provide a bowl having a et rim provided with a waterv trough to retain water and thus displace s-o much air thereby effecting a reduction of et noise as the flushing water fills the rim and overflows at the jet holes.

Also, to provide an air venting ejector or suction device utilizing the flushing water to effect an extraction of air from the bowl at a moment prior to the jet shower action.

And, further, to provide a reliable means for effecting a re-iill of the bowl with a substantially uniform volume of water.

Other objects, advantages and features of construction, combination, and details of parts and the method of action will be made manifest in the ensuing description of the herewith illustrative embodiment, it being understood that modifications, variations and adaptations may be resorted to within the spirit, scope and principle of the invention as it is more dire-ctlv claimed hereinafter, and which consists of the method and apparatus hereof and the equivalent.

Figure 1 is a vertical, longitudinal section.

Figure 2 is a horizontal section on line 2-2 of Figure 1.

The apparatus embodies a bowl 2 having a flushing rim 3 at the rear of which is a re-fill reservoir 4 receiving flushing water from a pressure supply pipe 5.

This pipe envelops the upper, open end of a downwardly convergent ejector nozzle 6 which is fixed in an ejector passageway 7 whose lower end passes beyond the basin 2a and upward toward the Siphon lip 2b under the basin.

The bowl has the usual Siphon down-leg 8.

The upper part of the passageway 7 opens under a hood 10 into the bowl space and when flushing water is turned on its high velocity jet causes a strong suction of air at its mouth; the inducted air and the water are forced over the water basin lip 2b and thence to leg 8.

The rim 3 has a trough 3a with divergent sides and this communicates freely with a well 11 which opens directly to the re-fill reservoir 4. The pipe 5 terminates above the level of the well top and quickly fills with water which backs up under resistance of the constant body of water in the trough 3a and well 11, which are on a level;

Around the innervwall of the trough is a ledge 12 which has a series of vertical perforations 13 discharging against the face of the bowl all around. i

The ejector nozzle 6 is in an inner wall ring 14 which keeps the trough wat-er from flowing down the vent passageway 7.

It will be seen that there is but a small air space in the rim and this is principally to allow for expansion of ice should the water freeze in the trough; this being more or less V-shaped.

In operation of the apparatus the flush water rushes to the nozzle 6 and ,thence to the outlet 2b and backs in the trough and in the reservoir until the jet openings are lilled and the water forced out therethrough. The nozzle ilow causes an induction af air at the mouth 10 from the bowl, this occurring a period just before jets flow from the rim holes 13. i

When the supply water is stopped the backed supply passesdown under air pressure in the reservoir until it falls to the level of the trough ledge and thus re-fills the bowl after the siphon action of the basin occurs.

lVhat is claimed is:

1. In a bowl of the class described, a flushing rim with a substantially V-shaped trough being imperforate at the bottom so as to hold water andan inner wallhaving aseries of downward jet apertures from the trough.

2. In a bowl of the class described, a flushing rim with a substantially V-shaped water holding trough and an inner wall having a series of downward j et apertures from the'top of the trougli,'and a re-till reservoir connected to the rim trough.

3. In a bowl of the class described, a flushing rim with jet apertures, and a re-iill reservoir communicating with the rim spaceand filling the bowl with 11e-till water through the rim.

4. In a bowl of the class described, a flush` ing rim with et apertures, and a re-till reservoir communicating with the rim space, and an ejector tube leading from said reservoir to the siphon passage of thev bowl indepen` dently' of the rim, and an air eduction mouth to the tube from the bowl.

5. In a bowlof the class described, a flushing rim with jet apertures, and a re-fill reservoir communicating with the rim space, and an ejector tube leading from said reservoir to the siphon passage of the bowl independentlyv of the riin, and an air eductioninouth to the tube from the bowl, and a water supply means leading to said tube and to said reservoir.

G. In a bowl of the class described, a flushing rim, and a communicating re-fill reservoir, an ejector tube, a water supply means opening toward the bottoni of the reservoir, anda noz- Zle embraced by the said means and leading into said tube. Y v

7. In a bowl of the Aclass described, a flushing rim and a basin washed thereby, an ejector passageway, to the basin, having its mouth in communication withV and adjacent to the rim chamber, and a water supply pipe which terminates close, and inaxial relation, to the said mouth so that a space is left for flow of water to the rim; whereby water is in principal part supplied to the passageway before the rim tiow is fully effective.

S. In a bowl of the class described, a flushing rim and a basin washed thereby, an ejector passageway, to the basin, having its mouth in communication with and adjacent to the rim chamber, and a water supply pipe which terminates close, and in axial relation, to the said mouth so that a space is'left for {io-w of water to the rim; whereby water is in principal part supplied to the passageway before the rim flow is fully effective, and a nozzlev whose intake end is disposed in, and in spaced relation to, the pipe end and leaving a passage to the rim chamber and which nozzle enters the mouth of the passageway.
